(01. 13242) The inv nt n relate to. improvements. inecurlins. rods, and more particular y. to-a, novelly .con- .Structed curling rod of .a ,kind, especially .use-ful for cold permanent waving. [.Inpermancntwaying ,of' the humanhair, and. particularly; in..the practice of that typecipermanentwavingknown as cold permanent waving, the. hairon'nthef head i divided into individual tresses .and .these tresse are woundupon curlingrods. .Eithenheioreor afterwin'dina,theltre es. oihairaresatuted with. p nnanent .hair .wavin solution which softens thehair or ,otherwise.,conditions it c a it wi lconformto its wound shape. The waving solution is allowed to ,rem ain aupon, the wound tresses of hair I101 a predetermined .pein of .time -and. it -'.is.subsequently washed. off with water or other like neutral solution.-

..fi i v l, .of; the waving solution .permits the hair to regain its initial; structural conditionrand after itphas been. removedfrom the curling. rod and dried, the stresses of. hair will remain. curled. Inipractice, it has been ,found ...that.s atisiace toryjresultsarebest obtained, when "using this method of cold permanent waving,.when;the..wav ing solution and theneutralizing solution. are periii) mitted to penetrate to the innermost.strands,- of

hair inithe wound tress so as toreffectrcomplete saturation thereof. In instances. whereccmp-lete satnrationuof all of thehairin the woundvtress is not effected, ,the finished curlirequently has portionsthereof .which do not remain. curled and asa consequence the,.finishe d curl is imperfect andjthahair dress, as a, whole is, nctunifcrm.

"It is, therefore,,an object .oirthepresentjnvention to provide, a, curling 170d usefulin peri manent waving of the hair which is. constructed in a noyelmanner. ,to ZiiaciIitatecQmmete,pener tration of; the perment .waving andneutralizing solutions, throughout the entire body of aria-air tress ,wound upon .said curling rod.

Another object, ,of the invention ,isto proyide a, curling rodof ,a kind .havinga shaped-cagelike body terminatin at its ends in ,novel fittings secured thereto in such manner as toi retain .the cageelike bodyin, its intended shape.

Another'object of the present invention is to provide a. curling rod of thercharacter referred to which embodies novel structural features anabling'-' the-waving -andneut-ralizing {solutions to pass freely therethrough and throughout'thebody tration, shows a preferred embodiment and the ill , 1T2 principlerthercof andwhich. is consideredrto be 'thebe'st mode contemplated forv applying-that principle.

The curllng; rodembodying. the. featuresaof the present invention consists generally vof l. a. shaped body-portion. and endfittings l l2. v.Thefloody portion l; l' preferably is fashioned substantially cage like 'and'it consists ,of a plurality of icircumferenti'ally spaced apart longitudinal bars. I 3, each-of whic-h'is curved longitudinallyso that, when mounted in. the manner illustrated, the medial portion of theycage-liketbody is contracted as shown. .Each of the bars l3 hasits'endportions .bent substantially .at .right angles to. the length'thereoftqprovide radial portions IA, and said'end -portions.are again bent to provide terminal portions l5 xtending outwardlyendwise substantially; parallel to but. in .a different plane than the. main portion .of'the bar L3.

"The end 'fittings l2 are identicaiandwasrbest shown in Big. 2 eachpreferablyzis fashioned'from round-"stock shaped toproyide two diameters i 1-6 and .H so as, to provide .an external annular shQulder 1'8 midway betweeniits ends. The portion of the ffitting l2 having lthesmaIler-diameter is bored axially, as at, L9, ,andlit. hast alplurality of circumf'erentiallyv spaced..lips 2 l: extendni-g-normall outwardly longitudinally fromsits ends. The lips 2| are, as mentioned hereinbeiiore, c'ircumierentially spaced .apart .so as to provide spacesfZZ'therebetween .each to receive-ztherethrough the radialend portion .14. of. one-of f-the ba-rsJl3-When assembled. When the bars iiiarepositioned: :with their .radial portions l4 extendiing between adjacent parts of'lips Zythf} longiw tudinally extending terminal portions I i xthereof proj set into the respective bores l9 and said E'bars i3iare firmly heid .in place by the lips 21 which are \bentover inwardly towards onc anoth'er, as best \shown..i-n-;Eigs. 2, -.-.4 and 5. This manner-r f mountingthe,barsJJ-and therendzfitting s l 2;pro-- vides a very rigid construction wherein the tenably by means of a clamp 23 pivotally mounted,

as at 24, on one of the bars i3. The curling rod is held at the end fittings l2 and-is rotated so as to wind the hair tress about the body thereof. When the hair tress is completely wound about the body I! the curling rod is then located .close to the scalp and the hair tress is secured against unwinding by any suitable means, such as by the use of a strand 25 of resiliently flexible material such as rubber or the like. The securing strand 25 has one end secured detachably to one end fitting 12, preferably by being provided withan aperture 26 adjacent an end of such diameter as'to fit snugly over the reduced diameter ll of the respective end fitting. The other end of the strand 25 likewise has an aperture 21 adjacent thereto which is engaged over the other end fitting l2. Inadvertent displacement of the securing strand 25, when connected to the end fittings in the manner described, is prevented by the resiliency of the strand itself which retains it taut and also by the provision of the shoulder I8 on each fitting which serves to prevent the respective end of the strand 25 from sliding outwardly off of the fitting engaged thereby.

It might be observed at this time that the cagelike structure of the bod H facilitates thorough penetration and complete saturation of the hair tress because its open construction enables the solution to flow freely throughout the entire bulk of the wound hair tress and through the interior of the curling rod body. Thus, when an excessive amount of solution flows through the uppermost portion of the wound tress it passes freely through the curlin rod and into those portions of the hair tress oppositely disposed thereto.

After the curl has been treated with the waving solution and with the neutralizing solution, it may be dried while remaining on the curling rod body II and then removed or it may be removed from said curling rod body prior to drying, easily and quickly by dis-engaging the securing strand 25 from either of the end fittings l2 and unwinding.

It should be understood that although the present disclosure teaches a preferred form of construction the number and cross-section of the bars 13 may be other than as shown and that other variations in detail construction may be made without departing from the spirit of the present invention and the scope of the appended claims.

8. A curling rod comprising a medially contracted cage-like body formed of a fitting at each end of said body, and circumferentially spaced bowed bars connecting said fittings, each of said bars having longitudinally extending offset terminal portions in substantial abutment, each of said end fittings having a recess to receive said offset terminal portions and having means for securing the same in said recess.

9. A curling rod comprising a cage-like body formed of a substantially cylindrical fitting at each end thereof, and circumferentially spaced bars connectin said fittings, each of said fittings having an axial bore and a plurality of circumferentially spaced lips adjacent thereto, said bars having terminal portions disposed between the said lips and extending into said bore, said lips being deformable inwardly to secure said bars to said fittings.
